Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 53,733,407, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 53,733,407 | |
| -1 | -53,733,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,733,407.
Example:
1 x 53,733,407 = 53,733,407
and
-1 x -53,733,407 = 53,733,407
Notice both answers equal 53,733,407
With that explanation out of the way, let's continue. Next, we take the number 53,733,407 and divide it by 2:
53,733,407 ÷ 2 = 26,866,703.5
If the quotient is a whole number, then 2 and 26,866,703.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 53,733,407 | |
| -1 | -53,733,407 |
Now, we try dividing 53,733,407 by 3:
53,733,407 ÷ 3 = 17,911,135.6667
If the quotient is a whole number, then 3 and 17,911,135.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 53,733,407 | |
| -1 | -53,733,407 |
Let's try dividing by 4:
53,733,407 ÷ 4 = 13,433,351.75
If the quotient is a whole number, then 4 and 13,433,351.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 53,733,407 | |
| -1 | 53,733,407 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 157 | 1,099 | 2,041 | 3,761 | 14,287 | 26,327 | 48,893 | 342,251 | 590,477 | 4,133,339 | 7,676,201 | 53,733,407 |
| -1 | -7 | -13 | -91 | -157 | -1,099 | -2,041 | -3,761 | -14,287 | -26,327 | -48,893 | -342,251 | -590,477 | -4,133,339 | -7,676,201 | -53,733,407 |
